CARBURETER.

Be it known that I, ALBERT C. MENeEs,'a citizen of the United States, residing at Grand 'g Rapids, in the county of Kent and State ofI Michigan, have invented new and useful Improvements in Carburet'ers, of which the following is a specification.

This invention relates to a new and useful carbureter, and isespecially adaptedifor the purpose of mixing the air with the vapors-of gasolene or similar f substances for preparing and feeding the explosive charge to an explo- The objects furnish an efcient carbureter for mixing the air and gasolene in order to provide a suitable explosive charge; second, to furnish means for'controllingthe valves which admit the air into the chamber, mixes the same with the gasolene, and discharges the same into the cylinder of the exposive-engine; third, to furnishl a simple and efficient means for operating a plurality of valves at the same time by means of a longitudinally-moving bar carrying suitable cam-surfaces; fourth, to provide means for adjusting the valve-throwlng devices separately and collectively; iifth, other objects which'- hereinafter described and claimed. These objects I accomplish by means of the mechanism illustrated in the accompanying drawings,in

'acts as a guide for thevalve-stem.

D is an opening in the valve-seat which acts as a guide for the valve-stem of the valve F.

E shows the stem and valve of the valve which-seats uponthe valve-seat having the openings C O, &c.,` and this valve E is held in lposition normally by means of the coiled spring E.

F is the valve which seats upon the seats having the openings D D, &c., and this valve is held normally in position by means of the coiled spring F. i

G is a tube having passages through which the gasol'ene passes to the carbureter. This lpart G also furnishes a support for the lioattank, and the lower portion of the part G is shown by n. g.

H is a needle-valve fitting into the tapering seat H (shown in Fig. 1) and adapted to close or open the passage which receives the gasolene into the carbureter.

I isa projection on the needle-valve H, against which the spring J abuts for the purpose of holding the needle-valve normally closed. 'g

K is the adjusting-nut on the needle-valve.

L is a bent lever fulcrumed at the point M, the fulcrum M serving as the attachment for rigidly connecting together the levers L and L', which levers are moved by the camV for the purpose of raising and lowering the needle-valve. l N is a collar upon the bar X 'and forms an abutment for the coiled spring Z, as shown in Figs. 1 and 2.

P is a pivotal fulcrum of the lever Q, said lever Q, being they lever used for raising the valve E, which admits `the explosive mixtur into the cylindervof the engine. v R is a fulcrum-pivotfor the'lever S, pivotally connecting said lever S to the case, and

vR is the hole into which the pivot R fits.

S is the lever, which lifts the valve F against the action of the spring F for the purpose of admitting the air into the chamber.

T is the curved portion of the lever S, Which engages with the cam W.`

IOO

U, V, and W are cams secured to the sliding rod Xand adjusted thereon, as hereinafter Y described.

X is a'sliding rod or bar upon which are attached the cams U, V, and W, said bar having a longitudinal motion for the purpose of moving the cams into position to open and close the valves E, F, and H.

Y is the turned or rounded portion of the sliding bar X, which is mounted in the journal X', only one of the journals being shown. X' also furnishes an abutment for the spring Z, the bar X being supported in bearings and is moved longitudinally by'any suitable means, carrying with it the cams U, V, and W, as above described. Any suitable means may be used for giving the longitudinal movement to the bar X and cams mounted thereon.

Z is a cap for holding in place the tubular portion G, and said cap also forms a bearing for the valve-stem of the valve H and an abutment for the spring J.

'Z is the cover of the float-tank.

Z is the oat-tank itself.

e is an adjusting-nut on the valve-stem g of the valve Z.

is a stationary sleeve on the float y', which sleeve t' surrounds the valve-stem g.

Z is an opening through which the gasolene passes to the passage-chamber when the needle-valve is raised, Za being shown in Fig. l.

j is the ioat.

Z is the valve for admitting the gasolene to the tank.

m is a threaded portion of the tank which receives the pipe which conveys the gasolene from some outside source into the tank.

nis the lower or bent portion of the tubular part G and is secured into the wall of the tank-chamber CZ.

r and r form a passage-way for the gasolene extending from the tank to the carbureter.

(shown in Fig. 6) is a modified form of one of the earns.

The cam U is pivoted at u and is adjusted by means of the slot u', a screw or bolt passing through said slot. rllhe cam V is pivoted at the point t and adjusted by means of the adjusting-screw c, passing also through a slot. The cam W is pivoted at w and adjusted by means of a screw passing through the slot w. In Fig. 6 the slot w/ is fully illustrated, also the general form of the cam. The three cams are all adjusted in a similar manner, being pivoted at the smaller end to the sliding bar X and adjusted at the larger end by means of a slot, a screw, or bolt, and the description -of one would serve for the description of the three cams.

In operation the gasolene from the main tank is forced into the tank-chamber by any suitable means and lifts the lioat j to a position just above the level of the outlet of the gasolene. The sleeve Z raises the valve-stem g by coming in contact with the adjustingscrew e and closes the valve Z. '.lhe gasolene is then allowed topass through the channels r r' and comes in contact with and passes through the needle valve H. When said needle-valve is raised by the cam V, the gasolene passes through the opening It. At the same time the valve F is raised by the cam W, permitting the air to pass into the chamber, mixing the same with the gasolene, and

`the valve E having been raised the explosive charge passes through the openings CC, 85e., into the cylinder of the engine at regular intervals. In Fig. l I have shown the passage of the air and explosive charge by means of the arrows 1, 2, 3, and 4.

By my construction the valve-operating mechanism can be adjusted with great accuracy. The three valves are opened and closed by a single action of the longitudinally-sliding rod or bar having the cam-surfaces. Each cam-surface can be adjusted independently for the purpose of accurately adjusting the throw of its corresponding valve, and the inclined surfaces of the cams may be readily changed to suit any required adjustment. By a proper adjustment of the inclines on the sliding bar the valve E and the valve H may be left open while the valve F is nearly closed. This causes astrong suction through the valve H, and when in this position the engine can be started without priming the ioat or carbureter. By this construction stufng a box having the needle-valve may be. dispensed with, and also screw-threads on the needle-valve are dispensed with.

Having thus described my invention, what IOO I claim to have invented, and desire to secure by Letters Patent, is-

1. In a carbureter, the combination of ashell or case having separated valve-seats therein, valves cooperating with said seats and having stems, the said valves controlling the admission of air and the outlet of the commingled air and gasolene, a gasolene-valve located intermediate of the said valve-seats and valves and regulating the supply of gasolene to the carbureter, movable projecting devices connected to the stems of the valves and located exteriorly of the carbureter, and a longitudinally-slidable rod having cams thereon with which the free extremities of the projecting devices loosely engage, the said projecting devices being normally outof engagement with respect to the cams and automatically returning to normal position when out of engagement with the cams to permit the valves to close.

2. The combination with a carbureter having valves for controlling communication between the several parts of the carbureter and provided with valve-stems projecting exteriorly of the latter, levers attached to the valve-stems and having `their free terminals Vdisposed in longitudinal alinement, and a lon- IIO gitudinally-slidable rod carrying a pluralityof cams to individually engage the free terminals of the levers, the levers operating to automatically open the valves when engaged by the cams and automatically returning to normal position when released from the cams to close the valves.

3. The combination with a carbureter, of valves controlling communication between the several parts thereof and the admission of gasolene thereto, and provided'with exteriorlyprojecting valve-stems, and a longitudinallymovable rod carrying a plurality of xed=cam devices which individually engage movable portions of the valve-stems' to automatically open the valves, the cams being normally disengaged from the valve-stems.

4. The combination with a carbureter, of inlet and'outlet valves therefor having valvestems projecting eXteriorly of thecarbureter, a gasolene-valve also having a stem projecting exteriorly of the carbureter between the inlet and outlet valve stems, and a longitudinally-slidable rod carrying a plurality of cams.

to individually engage portions of the stems of the inlet, foutlet and gasolene valves, the

valve-stems being normally disengaged from the 4cams, and eachcarn provided with means for independently adjusting the same.

5. The combination with a carbureter, of inlet and outlet valves therefor having valvestems, a gasolene-valve alsohaving a stem, a

free extremity to loosely bear on its corresponding inclined surface, for the purpose of throwing its valve open when the rod is moved longitudinally.

In testimony whereof I Lhave hereunto .set

Y*my hand in presence of two subscribing wit- IIGSSGS.
